Quick Tip: Line Length

Pages should be designed so the line length, the number of characters that appear per line, should be neither too short nor too long. Anything more than around 80 characters can introduce reading difficulties in scanning from the end of a line of text to the beginning of the next line. Short line lengths also introduce difficulty and vertical scrolling. The width of the body area of a web page should be constructed to ensure that lines of text are constrained to both minimum and maximum lengths across both small (such as mobile devices) and large screen resolutions.
